At a moved forward position, the lighting apparatus 2 may form a passage, that is, an air flow passage P, between the lighting apparatus 2 and the body 1 for the air to move to the air inlet 4. The room air is drawn into the air inlet 4 along the air flow passage P.
The body 1 may include a lateral direction discharge vane 22 to control an air flow rate being discharged through the lateral direction air outlet 6, and a lower direction discharge vane 24 to control an air flow rate being discharged through the lower direction air outlet 8.
The lateral direction discharge vane 22 may rotate around a vertical shaft, to open and close the lateral direction air outlet 6.

The air conditioner may include a lateral direction discharge vane drive mechanism 26 to rotate the lateral direction discharge vane 22, and a lower direction discharge vane drive mechanism 28 to rotate the lower direction discharge vane 24.
Each of the lateral direction discharge vane drive mechanism 26 and the lower direction discharge vane drive mechanism 28 may include a motor to provide a torque thereto. The lateral direction discharge vane drive mechanism 26 may include a left direction discharge vane drive mechanism 26A to rotate the left direction discharge vane 22A and a right direction discharge vane drive mechanism 26B to rotate the right direction discharge vane 22B.
The lighting apparatus 2 may be arranged in front of the air inlet 4. As the air inlet 4 is hidden by the lighting apparatus 2, an entire exterior appearance of the air conditioner may be improved. The lighting apparatus 2 may have a size formed larger than the air inlet 4. In this case, the air inlet 4 may be completely covered by the lighting apparatus 2. Thus, the lighting apparatus 2 may function as a decorative apparatus to enhance a decorative beauty of the air conditioner, or may function as a display that displays certain information with an illuminated image or a varying pattern of the illuminated image.
A lighting apparatus drive mechanism 40 may move the lighting apparatus 2 in the forward and backward direction. The lighting apparatus drive mechanism 40 may include a motor 42 to provide a torque, a driving gear rotated by the motor 42, and a driven gear engaged with the driving gear to move together with the lighting apparatus 2. The driving gear may include a pinion 44, and the driven gear may include a rack 46 engaged with the pinion 44.
To stably drive the lighting apparatus 2, a plurality of the lighting apparatus drive mechanisms 40 may be provided. According to one embodiment, the lighting apparatus drive mechanisms 40 may be provided on a left side and a right side of the lighting apparatus 2. When the air conditioner is operated, as the lighting apparatus 2 is moved forward by the lighting apparatus drive mechanism 40, the air flow passage P may be formed between the body 1 and the lighting apparatus 2.
The lighting apparatus 2 may include a lighting unit 70 to emit light, a base 50 to support the lighting unit 70, an illumination plate 60, a frame 80 having an opening 82 formed therein to expose at least a portion of the illumination plate 60 to an outside of the air conditioner and having a circumference thereof which forms a gap 78 to the illumination plate 60, and a reflective body 90 to reflect light emitted from the lighting unit 70 toward the gap 78. The base 50 and the frame 80 may be moved as one unit by the lighting apparatus drive mechanism 40.
The lighting unit 70 may include a plurality of light source elements 71. Depending on turning on/off patterns of the plurality of light source elements 71, an illuminated image formed on the illumination plate 60 may vary. The illuminated image may be formed on a predetermined path formed according to an array mode of the plurality of light source elements 71, and may move along the path according to the turning on/off pattern of the plurality of light source elements 71. Hereafter, though an example will be discussed, in which the plurality of light source elements 71 are arranged along a closed path (hereafter, referred to as annular path 0), and the illuminated image is also formed along a predetermined closed path matched thereto, embodiments are not limited thereto.
Though the plurality of light source elements 71 may be mounted on one circuit board, the plurality of light source elements 71 may also be mounted on a plurality of circuit boards 74. The plurality of circuit boards 74 may be mounted to an annular main circuit board 75, and the main circuit board 75 may be fixedly secured to the base 50 or the frame 80 with a supporter 79. The supporter 79 may shield the light emitted from the light source elements 71 incident on a rear side 63 of the illumination plate 60. By controlling lighting conditions, such as an order of turning on/off, colors, brightness, and so on of the plurality of the light source elements 71, a variety of illuminated images may be formed on the illumination plate 60.
The gap 78 may have a light transmission cover 30 arranged thereto for transmission of the light reflected by the reflective body 90. The light transmission cover 30 may be formed of a transparent, or semitransparent material that diffuses the light transmitted therethrough, providing a misty illumination.
The circuit board 74 may be arranged such that a side having the plurality of light source elements 71 mounted thereto faces the reflective body 90. Such a structure enables, not only to secure adequate light quantity incident on the reflective body 90, but also to shield the light incident on a side the rear side of the circuit board 74 faces, such that a center portion of the illumination plate 60 forms a dark portion which provides contrast with an outer portion of the illumination plate 60 adjacent to the gap 78, providing the misty illumination in which darkness is smoothly graded from the center portion to the outer portion of the illumination plate 60.
One circuit board 74 may have a plurality of the light source elements 71a and 71b mounted thereto. The plurality of the light source elements 71a and 71b may be turned on or turned off together, or turned on/off with time differences according to a predetermined turn on/off pattern. All of the light source elements 71 of the lighting unit 70 may embody different modes of animated illumination by a predetermined turn on/off pattern in which all of the light source elements 71 interact.
Though the illumination plate 60 may be formed of a non-transparent material, embodiments are not limited thereto. That is, the illumination plate 60 may be formed of a material having a predetermined transparency. However, even in this case, it is required that the light quantity transmitted from the rear side 63 to a front side 64 of the illumination plate 60 is lower than the light quantity incident on the front side 64 through the gap 78.
The illumination plate 60 may have a concave surface, for which a center portion of the front side 64on which the light transmitted through the gap 78 is incident, protrudes forward compared to a peripheral portion, to increase an area of light incident, enabling to make a distinctive contrast of the darkness between the peripheral portion and the center portion, and providing a three dimensional effect.
Each of the plurality of light source elements 71 may have controllable color and brightness. As a method for embodying a lighting color of the plurality of light source elements 71, an RGB color model is known widely in which a red color light, a green color light, and a blue color light are added in a proper ratio, to display a desired color. As the plurality of light source elements 71 which can express a color according to an input ratio of the red color light, the green color light, and the blue color light, there may be LED, LCD, for example. The plurality of light source elements 71 may display a color according to input of an array of R,G,B in which the ratio of the red color light, the green color light, and the blue color light is indicated with numerical values between 0 to 255. Each of the light source elements 71 may vary in brightness thereof with current intensity.
The color of the lighting may be defined with a visible light spectrum, relatively. A plurality of RGB color tables are known, in which colors are divided by using the RGB array. Each of the colors indicated on these color tables may be matched to a color classification with reference to the spectrum. For example, if a red color is defined to have a wave length of about 660nm, a green color is defined to have a wave length of about 532nm, and a blue color is defined to have a wave length of about 450nm, the red color, the green color, and the blue color defined by the RGB array may be defined as ones most close to the same colors on the spectrum within a wave length range which may be embodied by the plurality of light source elements 71. The colors classified according to the RGB array may be divided according to relative positions of wave lengths on the spectrum of the visible light matched to the colors. For example, an orange color light falls under a region between the red color light and the yellow color light, and indicated with the RGB array matched to the regions.
Moreover, if it is assumed that lighting of a blue color group or a red color group may be selected using the lighting apparatus 2, a color of the lighting emitted when the blue color group is selected is a predetermined color closer to the blue color on the visible light spectrum than when lighting of the red color group is selected, and, in an opposite case, a predetermined color closer to the red color. The plurality of the light source elements 71 may be arranged along a circle 0 substantially, such that each of the plurality of light source elements 71 emits the light to an outside in a radial direction, that is., radially, from a center of the circle 0.
The plurality of circuit boards 74 may be mounted to the main circuit board 75 spaced therefrom. The plurality of circuit boards 74 may be mounted to the main circuit board 75 to face directions different from one another. The plurality of circuit boards 74 may be mounted such that sides thereof are opposite to an inside periphery of the reflective body 70. The light source elements 71a, 71b may be mounted on one of two sides of the circuit board 74 opposite to the reflective body 90, and the light source elements 71 may direct the light toward the inside periphery of the reflective body 90. All of the plurality of the light source elements 71 may be turned on at a same time, or when some of the light source elements 71 are turned on, the rest of the plurality of light elements 71 may be turned off.
Hereafter, an image illuminated on the illumination plate 60 at a certain moment will be referred to as a 'descriptor', and a pattern of movement, formation, disappearance, shape change, color, and illuminance change of the descriptor may be referred to as an 'illumination pattern'.

The setting unit 100 may include an input to receive input on selection of the active lighting, information description lighting, therapy lighting, mood lighting, or object description lighting.
The active lighting may set an illumination pattern according to a surrounding environment at a time of turning on, wherein the surrounding environment may be a meteorological condition of a region, such as a room temperature, season and time, weather, sun rise/sun set, and/or an outdoor temperature, for example. For example, the active lighting may be applied to wake-up lighting, or sleep lighting. The air conditioner may include an input unit (not shown) to receive input on a setting of a scheduled time or a time of the wake-up lighting (or, sleep lighting), and the control unit 200 may control the lighting unit 70 to be turned on according to the scheduled wake-up lighting setting received through the input unit. In this case, the lighting described with the lighting unit 70 may have a pattern thereof fixed according to the surrounding environment of an embodying time point of the pattern (for example, a turning on time point of the lighting unit 70 due to arrival of the scheduled time). The wake-up lighting may provide an illumination pattern (hereinafter, a wake-up illumination pattern) which may remind a user of a morning sun shine, and the sleep lighting may provide an illumination pattern (hereinafter, a sleep illumination pattern) which may remind a user of moon light at dawn. The illumination patterns will be described in detail hereinbelow.
The information description lighting may be description of operation information, such as an operation state, and feed back on operation, instruction, order to the air conditioner, displayed with the lighting for a user to recognize, enabling the user to recognize the operation state of the air conditioner only with the lighting without an LCD or LED panel, or an output from a speaker, used in the related art. The information description lighting may include description of power on for putting the air conditioner into operation, power off for stopping operation of the air conditioner, putting a cooling/heating operation mode into operation, or shifting modes between the cooling/heating operation modes, changing a set temperature, changing an air flow rate, for describing a response (or, feed back) to reception of a predetermined control order at a time the control order is received from a remote control means, such as a remote controller, for example. Though not shown, the air conditioning unit may further include a reception unit that receives the control order, and the control unit 200 may control the lighting unit 70 and/or the air conditioning unit 400 according to the control order received through the reception unit. The pattern of the information description lighting (hereinafter, an information description illumination pattern) will be described in detail hereinbelow.
The therapy lighting is utilization of study results that lighting influences to the human body when colors of the lighting are varied.

FIGS. 11A(A) ∼ 11A(C) illustrate a wake up light pattern as an example of an active lighting, FIGS. 11B(A) ∼ 11B(C) illustrate a sleep light pattern as an example of the active lighting. The active lighting may be selected with the function selection module 110. FIGS. 11A(A) ∼ 11A(C) illustrate an illumination pattern in a case in which the wake-up lighting is selected as an example of the active lighting with the function selection module 110.
In the state in which the wake-up lighting is selected, a setting for the wake-up lighting selected thus may be input with the setting input module 120. As the setting for the wake-up lighting, there may be a scheduled turn on time, and a weather condition of the region at the scheduled turn on time. If the wireless communication module 700 is provided, the weather condition at the scheduled turn on time may be set in real time with wireless communication.
The pattern connecting module 230 may connect one of the illumination patterns stored in the storing unit 500 to the setting set with the setting input module 120. The storing unit 500 may store a plurality of pieces of illumination pattern information classified according to functions to be embodied with the lighting unit 70. Of the plurality of pieces of illumination pattern information, the pattern connecting module 230 may connect the illumination pattern information matched to the function set with the setting unit 100.
Upon arrival of the scheduled turn on time (a scheduled condition is met), the lighting control module 220 may generate a control signal according to the illumination pattern connected thus and apply the control signal to the lighting drive unit 300. If the weather of the region is reflected in real time, the connection to the wake-up illumination pattern, and the composition of the control signal according to the wake-up illumination pattern connected thus may be made according to a weather state at the time of arrival of the scheduled turn on time, or according to the weather state updated at a most recent time from the scheduled turn on time.
As the wake-up illumination pattern is for reminding the user of morning sunshine to induce a natural wake-up, it is suitable that the wake-up illumination pattern is a pattern of a warm color group, such as yellow, orange, and red. The color composing module 310 may drive the plurality of light source elements 71 to provide a light in the warm color group.
The wake-up illumination pattern may be displayed by turning on some of the light source elements 71 (see FIG. 11A(A)), and thereafter, the light source elements 71 around the light source elements 71 turned on thus may be turned on (see FIGS. 11A(B) and 11A(C)). Such an illumination pattern may be embodied by controlling turning on of the light source elements 71 with the luminance composing module 320. The lighting according to the wake-up illumination pattern may be performed repeatedly until there is a user's response (cancellation of the scheduled turn on time), or for a predetermined time period.
Referring to FIGs. 11B(A)-11B(C), the sleep illumination pattern is for reminding the user of a moon light to induce a comfortable sleep, and may be utilized when a scheduled condition, such as scheduled sleep or scheduled turn off is met. As the sleep illumination pattern, a pattern of a cold color group, such as blue or violet, is suitable. The color composing module 310 may drive the plurality of light source elements 71 to provide a light in the cold color group.
The sleep illumination pattern may be displayed by turning off some, or all of the light source elements 71 (see FIG. 11B(A)), and thereafter, the light source elements 71 around the light source elements 71 turned off thus may be turned off (see FIG. 11B(B)) until a predetermined number of light source elements are left on (see FIG. 11A(C)). Such an illumination pattern may be embodied by controlling turning off of the light source elements 71 with the luminance composing module 320. The lighting according to the sleep illumination pattern may be performed repeatedly until there is a user's response (cancellation of the scheduled turn off time), or for a predetermined time period.
FIGS. 12A(A) ∼ 12A(F) illustrate a feed back light pattern when a temperature is changed as an example of information description lighting. The air conditioner may include an input means to receive a user's setting on a desired room temperature, for the air conditioning control module 210 to control the air conditioning unit 400 according to the set room temperature to make the room temperature reach the set temperature. If the set temperature is changed through the input, the control unit 200 may display a feed back illumination pattern according to the temperature change. The feed back illumination pattern may be provided to notify the user of a regular input of the temperature change request through the input, and has an effect of performing a notifying function only with lighting without a separate display.
In more detail, of the illumination patterns in the storing unit 500, the pattern connecting module 230 may connect the feed back illumination pattern (hereafter, "temperature changing feed back illumination pattern") to a set temperature change, and the lighting control module 220 may generate a control signal according to the temperature changing feed back illumination pattern connected thus and apply the control signal to the lighting drive unit 300.
The temperature changing feed back illumination pattern may indicate an increase or decrease of the set temperature with a pattern of lighting of which a color varies. The color of the lighting may be classified into a warm color group which gives a warm feeling to a user, and a cold color group which gives a cold feeling. The temperature changing feed back illumination pattern may be a pattern of which a color temperature of the lighting makes transition toward a high temperature if a set temperature to be changed is higher than the present set temperature (increase of the set temperature), and opposite to this, if the set temperature to be changed is lower than the present set temperature (decrease of the set temperature), the temperature changing feed back illumination pattern may be a pattern of which a color temperature of the lighting makes a transition toward a low temperature.
For example, if the present set temperature is 18 degrees, the present set temperature is lighted with a blue color light, if 26degrees, lighted with a green color light, and 30degrees, lighted with an orange or yellow light. If a change of the set temperature is requested (request to change the temperature to 19degrees) with the input in a state in which the lighting unit 70 is lighted in a basic color (for example, white), in FIG. 12A(A), which indicates that the air conditioning is at the present set temperature of 18 degrees, the lighting is changed to a color in FIG. 12A(A) (a lighting having a color temperature between blue color and green color) corresponding to the present set temperature (For example, 18 degrees). The user can understand a level of the present set temperature from the color of the lighting, intuitively.
In the meantime, an amount of change of the set temperature (hereafter, a set temperature change amount) may vary with a number of inputs of the set temperature change amount through the input. For example, the set temperature change amount may be proportional to a number of pressing down of a set temperature change amount button. The lighting color may be changed as a response to each of the set temperature change requests, and the color of the lighting may be changed step by step reflecting the set temperature change amount corresponding to the number of change requests.
Thereafter, the lighting may make transition toward a color in FIG. 12A(C) (a lighting color having the color temperature closer to the green color) corresponding to a set temperature value (19 degrees) requested to change, and the lighting may be maintained for a predetermined time period in this state in FIG. 12A(D).
After the predetermined time period has passed, the lighting may be changed to white in FIG. 12A(F) which is the basic color, again. In this process, the lighting color may be changed to white, not instantly, but through gradation in which the lighting color is between the color corresponding to the 19 degrees and the basic color in FIG. 12A(E).
FIGS. 12B(A) ∼ 12B(E) illustrate an embodiment of a feed back light pattern when a flow rate is changed as an example of information description lighting. The air conditioner may include an input to receive a setting on a flow rate or strength of wind from the user, and the air conditioning control module 210 may control the air conditioning unit 400 according to the flow rate thus set. If the flow rate is changed through the input, the control unit 200 may display a feed back illumination pattern for the flow rate change. The feed back illumination pattern may be provided to notify the user of a regular input of a flow rate change request, and has an effect of enabling to perform the notifying function with the lighting without a separate display.
When the flow rate is changed through the input, the pattern connecting module 230 may connect the feed back illumination pattern of the illumination patterns stored in the storing unit 500 to a flow rate change corresponding thereto, and the lighting control module 220 may generate a control signal according to the feed back illumination pattern connected thus (hereafter, 'flow rate change feed back illumination pattern'), and apply the control signal to the lighting drive unit 300. In this case, the flow rate change feed back illumination pattern may be composed to display the brighter lighting as the flow rate increases. As described above, the luminance of the lighting may be controlled by the luminance composing module 320.
The flow rate change feed back illumination pattern may indicate an increase or decrease in the flow rate with a pattern for which luminance varies. If a flow rate to be changed is higher than the present flow rate (the flow rate increases), the pattern may transition toward brighter lighting, and, opposite to this, if the flow rate to be changed is lower than the present flow rate (The flow rate decreases), the pattern will make transition toward darker lighting.
In a state in which the lighting is the basic color (for example, white in FIG. 12B(A)) which indicates that air conditioning is underway, if a flow rate change (for example, flow rate increase) is requested through the input, a luminance of lighting may be associated to the present flow rate in FIG. 12B(B). The user may understand a level of the present flow rate from the luminance of the lighting, intuitively. Whenever the increase in the flow rate is input repeatedly thought the input, the luminance of the lighting may become brighter step by steps in FIG. 12B(C) and in FIG. 12B(D), and after the lighting with the luminance corresponding to the flow rate changed is maintained for a predetermined time period, the lighting may return to the basic color, again in FIG. 12B(E).
FIGS. 12C(A1) ∼ 12C(B3) illustrate another embodiment of a feed back light pattern when a flow rate is changed as an example of information description lighting. The flow rate change feed back illumination pattern may be embodied with animated lighting in which a predetermined descriptor may change a position on the illumination plate 60. A moving speed of the descriptor may be set to vary with a set flow rate, wherein the higher the set flow rate, the faster the moving speed. By turning on an array of the light source elements 71 in succession and turning the array off in succession, starting from ones turned on first, a mode of the lighting may be embodied in which a descriptor P moves in a fixed direction of FIG. 12C(A1) →FIG. 12C(A2)→FIG. 12C(A3). The descriptor P may be certain turned on ones of the plurality of the light source elements 71 arranged to form a closed path circulating the closed path. In this case, a fore end P1 of the descriptor P heading in the moving direction may be the brightest, and a rear end P2 of the descriptor P may be the least bright, such that the brightness is graded in a section between the fore end P1 and the rear end P2, in which the brightness gradually decreases as the light source elements 71 go from the fore end P1 to the rear end P2.
FIGS. 12C(A1) ∼ 12C(B3) illustrate a mode in which a turned on descriptor P circles in a clockwise direction within a section (about 1/4 of a circle). At a time of the flow rate change, though the descriptor P may circle a predetermined number of times for a predetermined time period, a speed of circulation may vary with a level of the flow rate thus changed. In this case, if the flow rate change feed back illumination pattern is performed, that is, if the flow rate setting is changed in the middle of the circulation of the descriptor P, the circulation of the pattern performed presently will end, and a new flow rate change feed back illumination pattern having a circulation speed of the pattern changed according to the changed flow rate may be performed.
In a state in which the lighting is the basic color (for an example, white in FIG. 12C(B1)) which indicates that air conditioning is underway, if the flow rate change or a flow rate indication request (this may be a first request of a plurality of flow rate increase requests through the input) is received through the input, the descriptor P may be circulated at a speed corresponding to the present flow rate, in FIG. 12C(B2). The user can understand a level of the present flow rate from the circulation speed of the lighting, intuitively. Thereafter, if an increase in the flow rate is received from the input again, the circulation speed of the descriptor P may change, in FIG. 12C(B3). The circulation speed of the descriptor P may vary with increase/decrease of the flow rate thus requested.
FIGS. 12D(A) ∼ 12D(C) illustrate an embodiment of a feed back light pattern as an example of information description lighting. This embodiment suggests changing a color of some of the light source elements 71 in the illumination pattern as a response (feed back) to the user's input. Though this is suitable for notifying regular reception of a predetermined control order through the input, such as the remote controller, embodiments are not limited thereto.
For example, if the predetermined control order is received through the input in a state in which the lighting is a certain basic color (for example, a blue color), some of the light source elements 71 may be returned to an original basic color again after being changed to another color (for example, a white color) in FIG. 12D(B). Some of the light source elements 71 may be used as the descriptor P which notifies the feed back.

The illumination pattern (hereafter, "cooling operation starting illumination pattern") when the room cooling operation is performed may be an illumination pattern in a case in which the room cooling operation is started from a state in which power is turned off. In order to allow a user to know by instinct that the operation is the room cooling operation upon seeing the color of the lighting, the cooling operation starting illumination pattern may include a step of turning on the light source elements 71 in a cold color group.
Referring to FIGS. 13(A1) ∼ 13(A4), upon reception of a room cooling operation request through an operator, such as the remote controller, in a state in which power is turned off, the light source elements 71 may be turned on in a blue color slowly, as shown in FIG. 13(A1), all of the light source elements 71 may be turned on at a fixed luminance, as shown in FIG. 13(A2), the lighting color may be changed to a basic color (for example, a white color) slowly after a predetermined time period has passed, as shown in FIG. 13A(A3) and FIG. 13(A4), and thereafter, white color lighting may be maintained during the room cooling operation as shown in FIG. 13(A5).

The air conditioner according to embodiments suggests a change in the lighting made different depending on kinds of air conditioning operations performed at a certain moment when a power turn off request.
Referring to FIGS. 14(A1) ∼ 14(A4), when power turn off is requested in the middle of the room cooling operation through the operator, such as the remote controller, the light source elements 71 may be turned on in the cold color (hereinafter, as an example, a blue color) slowly, as shown in FIG. 14(A1) and FIG. 14(A2), blue color lighting of a fixed luminance may be maintained for a predetermined time period, as shown in FIG. 14(A3), the lighting may be darkened slowly, as shown in FIG. 14(A4), and the lighting may be turned off (a power turn off state).

Referring to FIGS. 15(A1) ∼ 15(A5), upon receipt of the room heating operation request in the middle of the room cooling operation (a lighting color at this time may be a basic color, for example, white color) through the operator, such as the remote controller, the light source elements 71 may be turned on in the warm color group (hereafter, using an orange color, for example) slowly, as shown in FIG. 15(A1). In this case, all of the light source elements 71 in a state of being turned on in the white color do not chang to the orange color at a same time, but rather, a plurality of the light source elements 71 arranged to form the predetermined closed path, may be gradually changed to the orange color slowly starting from ones arranged on a lower side thereof to ones arranged on an upper side thereof in succession, as shown in FIG. 15(A2). Accordingly, an annular bright portion formed on the illumination plate 60 may be changed gradually starting from a lower side to an upper side thereof.
When a predetermined time period has passed in a state in which all of the light source elements 71 are turned on in the orange color, as show in FIG. 15(A3), the color of all of the light source elements 71 may become lighter gradually, as shown in FIG. 15(A3) and FIG. 15(A4) until the color changes to a white color which is the basic color, in FIG. 15(A5).

In the meantime, the therapy lighting may be selected with the function selection module 110. Input of the setting on the therapy lighting thus selected may be made through the setting input module 120. In the setting on the therapy lighting, there may be a color, a luminance, scheduling of turn on, and a turn on time of the lighting of the illumination pattern, for example. Though input of the setting may be done by the user, if there is no separate setting, the setting may be made according to a setting made already and stored in the storing unit 50.
The pattern connecting module 230 may connect one of the therapy illumination patterns stored in the storing unit 500 to the therapy lighting selected with the function selection module 110. If there is a setting input through the setting input module 120, the pattern connecting module 230 may connect a therapy illumination pattern taking the additional setting into account. In this case, the pattern connecting module 230 may change the therapy illumination pattern existing in the storing unit 500. For example, if colors of a pattern are received from the setting input module 120, colors of an existing therapy illumination pattern may be revised. The lighting control module 220 may generate a control signal according to the illumination pattern connected, and apply the control signal to the lighting drive unit 300.

FIG. 21 is a graph showing comparison of preferences by ordinary persons and depressive disorder patients. Functions and effects of the therapy lighting will be described.
The therapy lightings will be described, with reference to FIGS. 16(A) to 16(D). FIGS. 16A(A) ∼ 16A(D) illustrate a pattern of blood circulation acceleration lighting as an example of the therapy lighting. The blood circulation acceleration lighting has a lighting-up pattern which is a combination of colors based on an orange color light, a yellow color light and/or color lights existing between regions of above colors in a visible light spectrum. The colors may be displayed in circulation.
Between lighting-up of the orange color in FIG. 16A(A) and the yellow color in FIG. 16A(D), the colors in FIG. 16A(B) and FIG. 16A(C) existing in a middle region of above colors in the visible light spectrum may be lighted-up. Each of the color lights may have a luminance that increases gradually in lighting-up, and decreases gradually in turning off for lighting-up a next color light.
The blood circulation acceleration lighting has effects of accelerating blood circulation in a human body, making a circulation system smooth, invigorating an endocrine system and a digestive system to improve natural healing capability, and enhancing active energy.
FIGS. 16B(A) ∼ 16B(C) illustrate a relaxation lighting as an example of therapy lighting. The relaxation lighting has a lighting-up pattern which is a combination of colors based on a green color light, a blue color light and/or colors existing between regions of above colors in a visible light spectrum. The colors may be displayed in circulation.
Between lighting-up of the green color light in FIG. 16B(A) and the blue color light in FIG. 16B(D), colors in FIG. 16B(B) existing in a middle region of above colors in the visible light spectrum may be turned on. Each of the color lights may have a luminance that increases gradually in lighting-up, and decreases gradually in turning off for lighting-up a next color light.
The relaxation lighting has colors which give hope and stability, ease tension enabling balance, and have a calming effect to be effective for concentration and insomnia. The relaxation lighting also gives a feeling of satisfaction, not only improving business ability, but also is suitable for taking a rest due to it being cozy colors.
FIGS. 16C(A) ∼ 16C(C) illustrate a mediation lighting as an example of therapy lighting. The mediation lighting has a lighting-up pattern which is a combination of colors based on a violet color light, a pink color light and/or colors existing between regions of above colors in a visible light spectrum. The colors may be displayed in circulation.
Between lighting-up of the green color light in FIG. 16C(A) and the blue color light in FIG. 16C(C), colors in FIG. 16C(B) existing in a middle region of the above colors in the visible light spectrum may be turned on. Each of the color lights may have a luminance that increases gradually in lighting-up, and decreases gradually in turning off for lighting-up a next color light.
The meditation lighting gives purification and stability mentally, and acts on the parasympathetic nerve and pituitary gland. In particular, a violet color is good for moderation of pain, or healing of shock or morbid fear due to effects of giving an influence to a brain and a nervous system to calm down an oversensitive symptom. Further, it is well known that the pink color is a color of understanding and kindness representing maternal love. The pink color has an effect of calming down, suppressing secretion of norepinephrine which causes an aggressive action in the brain and body.
In the meantime, the mood lighting may be selected through the function selection module 110. A setting on the mood lighting thus selected may be input through the setting input module 120. As the setting on the mood lighting, there may be a color, a luminance, scheduling of a turn on time, and a turn on time period of the lighting of the illumination pattern. Though the setting may be input by the user, if there is no setting, the setting may be according to a setting made already and stored in the storing unit 500.
The pattern connecting module 230 may connect the mood lighting selected through the function selection module 110 to one of the mood illumination patterns stored in the storing unit 500. If there is an additional input through the setting input module 120, the pattern connecting module 230 may connect the mood lighting to one of the mood illumination patterns taking the additional input into account. In this case, the pattern connecting module 230 may also change the mood illumination pattern existing in the storing unit 500. For example, if colors of the illumination pattern are input through the setting input module 120 of the setting unit 100, the colors of the mood illumination pattern existing presently may be revised. The lighting control module 220 of the control unit 200 may generate a control signal according to the illumination pattern thus connected, and apply the control signal to the lighting drive unit 300.

Though FIGS. 19(A) to 19(E) illustrate rectangular abstract art paintings, the objects displayable with the lighting are not limited to this, but a variety of objects may be described depending on arrays of the lighting source elements 71. The object to be displayed may be selected with the function selection module 110. Depending on embodiments, the object may be selected in the middle of an air conditioning operation, as shown in FIG. 19(A). In this case, the lighting indicating that the air conditioning operation is underway becomes darker slowly, as shown in FIG. 19(B) until the lighting is turned to the color of the object, as shown in FIG. 19C.
A setting on the object thus selected may be input with the setting input module 120. The object intended to be displayed may be selected with the setting input module 120. If there is no separate setting input with the setting input module 120, the setting will be according to a setting previously set and stored in the storing unit500.
The pattern connecting module 230 may connect the object selected with the function selection module 110 to one of the object illumination patterns stored in the storing unit 500. If there is an additional input through the setting input module 120, the pattern connecting module 230 may connect the object to one of the object illumination patterns taking the additional input into account. In this case, the pattern connecting module 230 may also change the object illumination pattern existing in the storing unit 500. For example, if the object intended to be displayed input with the setting input module 120 is changed, the object illumination pattern stored in the storing unit 500 may be changed.
The object may be embodied with a pattern based on colors of the object intended to be displayed. FIGS. 20(A) to 20(F) illustrate an example of such illumination patterns for describing an object based on an orange color 1, a pink color 2, a red color 3, and a green color 4, wherein, if the object is selected in a state in which the lighting unit 70 is lighted in the white color (the basic color), colors may be lighted in an order of the orange color, the pink color, the red color, and the green color.
A change from one color to another color may be performed by, after a luminance of one color is darkened slowly, as shown in FIG. 20(B), the luminance of the other color may become bright until the luminance gradually becomes a predetermined level. The lighting having reached the predetermined luminance may be changed to a next lighting while slowly darkening again.
It is not required to turn on all of the light source elements 71 in the same color at one time, but two or more colors may bedisplayed. In this case, after some of the light source elements 71 are changed to the next color, first, colors surrounding the changed light source elements 71 may be changed in succession making an area displaying the changed color gradually larger while reducing an area of the color unchanged gradually (see FIGS. 20(A), 20(E), and 20(F)).
